All of a sudden I'm not getting any sound out of my Zapco DC360.4. It's powered on but no sound comes out. I've checked the source signal feeding the amp, and it's fine. So it is being fed sound.

I also noticed, before it failed, that I was getting weird garbled, artifact sounding audio through it. Which makes me think the DSP was acting wonky. Is there a hard reset for the whole amp somewhere? I'm looking in the manual, but not seeing anything.

I'm most likely going to yank it out and replace with a JL amp and CS - But thought I'd check here first.

Thanks all!

There isn't any kind of reset. Just need to send in to Zapco for repair.
